| Hi Everyone
New to the Forum - I already received GREAT help in the wanted to buy section - And have a poly 4bbl intake coming in from California
Now I'm seeking help concerning -- Brand Names - Part Numbers etc. - for ARP type HEAD bolts or studs
NO LUCK Thus Far -
I found the 318 Compatible ROD and MAIN ( ARP ) Bolts Jegs or Summit -- JUST no luck on the HEAD BOLTS
If no such animal exists ---
My guess would be to take my old bolts to a BOLT retailer - And match them up with GRADE "9" not 8
Or Chrome Moly Bolts (Cap Screws lol)
THANKS EVER SO KINDLY FOLKS - DON
1956 SAVOY 4dr |

Location: WHEELING,WV.>>>HOME OF WWVA | unless the head bolts are ate up or the motor has gone through way too many rebuilds , why not use the old ones . finding new replacements might be a huge chore and
a pretty good expense especially when replacements weren't needed . i can understand new but not when old is perfectly fine --------------------------------------later |

| THANKS MUCH GUYS - The old bolts seem to be fine - But I'm going a bit hotter with the cam - From Cam Craft from NC.
So I thought fresh bolts would be the way to go |

An engineer will tell you to replace the bolts, as the bolts will have stretched and would, therefor be no good, as they would now be weaker.
In the real world (as Chuck said), unless you building a monster engine thats going to get huge combustion chamber pressures (blown ect), go with the ones you want.
Thats unless you want to go with the head stud look or change all the bolts to cap bolt style (ellen key headed) or something like that?

When I built my engine, the machinist wanted me to get different ratio rockers, so I got more valve lift, but I never looked into it
You might need alloy rocker covers for clearence

Barrett Lash has been developing this Poly 318 for quite some time. Engine has many modifications and custom parts. I will post a copy of the Dyno pulls once I receive them, hoping second week in Sept.
This is Barrett Lash's 4rth and final build of the motor that has been his
test-bed of ideas to make the poly really perform. The 1st project build
was done in 1980, had 318 cubes, a Racer Brown Solid Cam and a single 4
barrel. It pushed the 4000# 66 fury to 14.30s (about 1hp per cubic inch).
31 Years later: it is now 362 CI, has a Milodon gear drive, hydraulic
roller cam, custom billet roller rockers, Hogan Sheet metal Manifold and
several hundreds of hours in head and block prep. With the Fury now down
to 2800#, Barret expects to do alot better than 14s....and for those who
say the POLY can't make big power to shut up!
